Oil changes on a low mileage diesel PU
I'm going to average about 4,000 miles per year on my Ram 3500 diesel. So, at the end of my 36 month warranty, I might have 12,000 miles. According to the service manual, I am supposed to change my oil at 6 months if I don't hit the mileage limits, which I won't even come close to reaching.
So, at the end of 3 years, Ram wants me to have done 6 oil changes on an engine that might have only 12,000 miles on it ?!?! Really? That oil sat in the ground since the Jurassic era, about 230 million years ago. What, they think it's going to turn bad in 3 more years sitting in my crankcase? There is no validity to that whatsoever. Nobody can present evidence that anything bad will happen to oil sitting in a crankcase in that time period. Lot's of opinions about it, but no evidence. Change oil 6 times in 12,000 miles to keep a warranty valid? Silly...
What do you guys think I should do?
I'm thinking if they ever tried to reject a warranty claim, an oil sample analysis would easily show it was not an oil caused problem, and that the oil was still well within tolerable limits.
I could even live with once a year, though even 3 oil changes in 12,000 miles is scientifically excessive by any standards.
